Why was emory paper in the mint in the first place? These emory discs were used at the Mint in treating the dies, which had a problem in 1986 and 1987 with planchets sticking to them. 3M emory discs were used to treat the die surfaces, and were struck between a planchet and the obverse die, and then the same was done to the reverse die, and in doing this process the problem with the planchets sticking to the dies was resolved. Apparently in 1987 the problem was resold, which is why struck emory discs are only known for 1986 and 1987 dated American Silver Eagles.The emory discs were supposed to be destroyed, but a number of them made it out of the Mint. Although no one knows for sure, there appears to be a population of 50-100 of these in existence, with most of them hoarded away in collections.
For an incredibly popular coin series, that is a tiny population, and is a 2-year only issue 1986 and 1987.
